AMD FidelityFX Super Resolution (FSR) Plugin for Unreal Engine 4 Released

AMD released the FidelityFX Super Resolution (FSR) plugin for Unreal Engine 4, allowing game developers to integrate the performance enhancement technology with their games. A competing technology to NVIDIA DLSS, FSR lets gamers improve frame-rates of their games by trading off quality. At the higher "Quality" presets, this quality loss is supposed to be practically unnoticeable, but with significant improvements to frame-rates. We detailed how the technology works in our article that gets under its hood and evaluates performance. At its launch, AMD listed out a broad list of launch partners for the technology, but Unreal was a notable absentee. Over the following months, AMD appears to have worked toward bringing the tech to even UE4. The plugin is being distributed through AMD's GPUOpen portal.

Some wisenheimer is going to come along and say, "but we're on UE5 now, get with it AMD!" So I'll just get that out of the way.

Very happy to see FSR come to UE4. It's a popular engine, and can be a dog on the hardware requirements sometimes. Hopefully we see those games still being developed on UE4 with TBA release dates pick this up as a standard setting. Give those with aging or less powerful PCs a chance to enjoy those new games they've been working so hard on.

Actually you are right. Most of them including me started using UE5 thanks to nanite and world partition and DLSS plugin is already there. I am using it. Would love to add this as well.

I hope that some of UE4 game that do not run very well just load this plugin. Simple performance boost for small studios that do not have the skill or the time to optimise their game better.

and you don't use TSR? does FSR would still make sense ?

All these technologies, from DLSS, FSR, Nvidia scaling, Sharpening, etc are making games blurry

This was not what I wanted from PC hardware future. If in 2010 (when we already played 1080p 120hz easily), you asked me what could we have in 2021, I would say at least 4k 240hz or 8k 120hz, miniLed monitors, almost zero blur and input lag, with max 300w GPUs.

Just saying

We would have all wanted that...

Sharpening solution do not make game blurry, it's actually quite the opposite. As for the other solution, they can make game blurry, but good implementation at higher resolutions are not blurry in higher quality mode. But it indeed depend on pixel density and how far you are from the screen.

on a 4K 27 inch, you might not even see if the game use higher quality upscaling mode like DLSS quality or FSR ultra quality. But you might notice it if you play at 1440p on a 32 inch...

But those technique allow 2 things

1. Ability to run higher details on lower end or Older GPU
2. Ability to run higher resolutions without lowering the details (or just at all)
or both.

But as of now, those are optional and if you want to run your game without. You can, you can always lower the resolution or the details or get a Halo GPU to get maximum FPS. You can also play older games that have no problem to run.

Only if you use the highest settings

With the exception of DLSS quality that actually improves many games, think of it as a reverse AA: It's for people who want higher FPS, on weaker hardware.

How many GPU's got scrapped cause they couldn't keep up, but would now last years longer in a kids machine with DLSS/FSR?

I wonder if this really makes it even easier to put into games, and if so, I hope devs still give appropriate time to tuning FSR, namely at least the default sharpness value (but still give us a sharpness slider!) per title.

for older ones yeah

A single patch, some new media attention and they can get a bunch of new players on hardware too weak to play it well before - it's win win for both game devs with older titles, and for AMD
